Axcess to netlinx

alanh

Previously in axcess programming if you had 6 (number doesn't matter could be any number) identical devices you could use a variable i.e selected_camera, in your code you could them use selected camera = 5 and in your push statement you have

send_string selected_camera,"$01,whatever"

where selected_camera transmitted out on port 5 or whatever port selected_camera =

How do you achieve this in netlinx,

any help greatly apprecited.

The easiest way that i know of is to put the 6 devices in a dev array.
You then use the index to point to which device to send too.

define_device

(* RS232 *)

dvCamera1				= 3:1:1			//  Axcent Slave Frame Port 2
dvCamera2				= 4:1:1			//  Axcent Slave Frame Port 3
                   
dvCamera3				= 5001:1:1		// NI Port #1
dvCamera4				= 5001:2:1		//  NI Port #2
dvCamera5				= 5001:3:1		//  NI Port #3
dvCamera6				= 5001:4:1		//  NI Port #6
                                              
dvTp 						= 10001:1:1

define_variable

volatile dev cameras [] =
{
	dvCamera3,
	dvCamera2,
	dvCamera1,
	dvCamera4,
	dvCamera5,
	dvCamera6
}                    


volatile integer selectcamera []
{
	21,22,23,24,25,26
}


define_event

Button_event[dvtp,selectcameras]
{
	push:
		{
			stack_var integer k
			k = get_last (selectcameras)
			
			send_string cameras[k], "'DO THIS COMMAND'"
		}
}

The trick to remember here is everything is based upon what position in the array you put it.

Hope this helps

Thanks

Will give it a try.
